IMPROVEMENT IN WATER-METERS.f

specification forming part ofLetters Patent No. 131,929, dated october e, 1872; animated october 5, l1872.

To all whom it may concern: Y

Be it known that I, HENRY M. BARTLETT, of South Dedham, in the county of Norfolk and Stateof Massachusetts, havev invented certainV Improvements in Water-Meters, of

Y which the following is a specilication:

Figure 1 of the drawing isa central vertical longitudinal section of my improved water or tion in water-meters, patented by me September 19, 1871, whereby -the operation of the same is simplified and a more economical and effective meter is produced. My improvements consist mainly in operating, by a radial action, .a transverse sliding valve-piston in connection with a longitudinal main valve-piston, each .supplied with a peculiar arrangement of ports,

channels, and valvesas will be more fully explained hereafter-seas to produce areciprocal motion that will actu'ate proper registering devices connected with a meter.

In the drawing, a a represent a cylinder provided with supporting-heads b b 'b' b', which form bearings for a rod or piston, c, that has aradiatin g wing, d, which revolves with it and acts on either end of a curved transverse slide, e, which travels through and is supportedin slots ff', formed in the `upper portion of the angular sidesg' g of a longitudinal abutmentchamber, g g, extending the length of the cylinder a a, and formed by the angular Sides g g, and a segmental bottom extendingover the top of the rod c, and closed at the ends by the heads b b', through the latter of which an eduction-pipe, h, connecting with the abut-` ment-chamber g g, passes. The curved transverse slide e is provided with a vertical stem, fi, that extends up from its top and connects with a Socket, k, .formed on and extending downward from the under side of avalve, O, which slides 1tran sversely on and is held by the upward extended Sides of a curved bridge, ll,

.which is formed with a central square port, um, and two side ports, n n', arranged transversely with the bridge H, which is formed on the top p p of a portion of the meter that extends up fram the cylinder a a, forming longitudinal chambers or channels q g between the top of the cylinder a a andthe bottom and Sides r r of the upper portion p p of the meter. The upper portion p p is provided with a longitudinal exhaust-port, s, which connects with the abutment-chamber g g and its eduction-pipe h, and has two longitudinal ports, t t', on each side of the exhaust-port s, connect- .ing with the interior of the cylinder a a. The channels q qare each provided with longitudinal ports u u', formed in the top of the upper portion p p of the meter, and connecting vwith the ports n n of the slide-valve O. Slidingtransversely on the upper portion p 1o of the meter, so as to open or close the ports s t t -and u uf, is a semicircular main valve-piston, F, formed with longitudinal ports o fvf,

'formed in its periphery above two side transverse ports, z z, and a central dome-valve, z, formed parallel with the ports z z. The main or valve-piston F is provided at each end with projecting stems y y', which act against bumpers w w', formed on the inside of semicircular vheads AA, attached tothe Sides 1' r of theupper portion p p, and flanges B Bf, formed on the ends of a semicircular case, C, that is attached to the upper portion p p ofthe meter, and lits over the main" valve-piston F, and has formed on it a case, D, that covers the sliding valve O, `and iS provided with an'inductionpipe, E, attached to its front. The side of the case C forms a partition, Gr, which is provided with a port, H, formed longitudinallygwith Ithe valves O F, and divides the cases G and D into chambers I and K,

The operation of my improved meter is as follows: The water or other fluid entering through the induction-pipe E, passes through the pressure-chamber I into one of the ports n or n of the sliding valve O, and thence into one of the channels g and through the port u, is brought to bear against one end of the main valve-piston F, causing it to travel to the opposite side of the meter, and, opening the port t, through which the water or other fluid passes, and pressing against one side of the wing d, causes the rod or piston c to revolve and carry the wing d around to the opposite side g of the abutment g g, thus striking the other end of the curved slide e, and carrying the slide-valve O and opening its opposite port n',

thereby causing ythe water or other uid to c renten pass into the channel q', and through the port u', and operate against the other end of the main valve-piston F, thus forcing it'back to one side to the other, thus actuating the slide c so as to produce a continued reciprocating movement to the valves O and F, by which any suitable indicating device connected with the meter may be operated.

The channels q q are direct in their communication from the valves O and F through the ports n n to the ports u u', instead of bein g cross-channels, as in my previous patent; and instead of forming the valve-piston F with two exhaust-spaces, as formerly, it is arranged, in the present instance, with but one exhaustspace, 2; thus eeonomizing labor and material in the construction, and, by the arrangement of the several devices hereinabove described, producing a meter effective in its operation.

Having thus fully described my improvements, what I claim asmy invention, and desire to have secured to me by Letters Patent,

l. A water or other fluid meter provide with a radial Wing, d, revolving with a rod or piston, c, against either end of a curved transverse slide, e, so as to operate reciprocally back and forth transversely with the meter, a sliding valve, O, and a main valvepiston, F, and open and close ports s, t t', u u', o t', z z', a n', and m, by the action ofthe water on the said Wing d through the said ports and channels q q', chambers g g l K, pipes E h, and port H, so as to regulate and correctly indicate, on a suitable registering device connected with the meter, the iiow of Water or other iiuid passing through the same, substantially as specified.

2. The rod or piston c, provided with radial wing d, operating against either side of abutment-chamber g g, in combination with slide e, bridge ZZ, and sliding valve O, substantially as specified.

3. The cylinder a a, formed with upper portion 1o p, provided with curved bridge l Z, ports ma a s t t u u', and chambers or channels q q', abutment-chamber g g, heads b b b'b', in combination With the rod or piston c, Wing d, valve O, and main valve-piston F, substantially as specified.

4. The sliding valve O formed with socket lo, and traveling forward and back on the bridge l l, transversely with the meter, so as to open and close the ports n n', in combination with slide e, piston c, and cylinder a a,`s'ub stantially as specified.

5. The main valve-piston F, formed with Y longitudinal ports o o', transverse ports zz', dome-,valve z, projecting stems y y', and operatin g parallel with the sliding valve O transversely back and forth on the meter, in com bination with the valve O, piston c, slide c, cylinder a a, and cases UD, substantially as specified.

-6. The case C, attached to the top of the meter and formed With projecting case D, partition G, port H, eduction-pipe E, chambers I K, iianges B B', heads A A', and bumpers w w', in combination with main piston-valve F, sliding valve O, and cylinder a a, substantially as speciied.

7. The curved transverse slidec, provided with stem z' traveling in slots ff, in combination with sliding valve O, piston c, Wing d, and abutment g g, substantially as specified.

8. The abutment-chamber g g, formed with angular sides g g, slotsff, in combination with piston c, Wing d, cylinder a a, valve O, main valve-piston F, and cases C D, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence o f two subscribing Witnesses.

HENRY M. BARTLETT.
